BACKGROUND OF THE INVENTION

This invention relates to method to produce activated liquid which contains micro gas bubbles and new methods realized by the use of the liquid, and is applicable to the purification of the liquid in polluted seas, lakes and marshes, dams, rivers etc., or drinking water, industrial water, agricultural water, cooling water and waste oil discharged from factories and gas stations etc., cleaning and sterilization of food, i.e. agricultural and marine products, medical treatments, the extinguishment of undesirable bubbles, preservation of freshness of food and the storage of gas such as hydrogen, carbon dioxide, methane etc., in liquid.

In addition to the known characteristics of water purification, micro gas bubbles defined to have diameter less than 10 micrometers contained in activated (ionized) liquid was experimentally found by the inventor of this invention to exhibit novel characteristics such as the extinguishment of larger bubbles especially those mixed in viscous liquid, storage of hydrogen, carbon dioxide and methane etc., preservation of food, vegetables and meat for longer period, sterilization, medical treatment, safer and more efficient spray for fire extinguishment, moistening, manure, fertilization of soil, and more efficient purification of polluted liquid utilizing the effects, i.e. enlarged contact area of gas with liquid, decrease in surface tension, generation of hydroxyl ion and micro clusters caused by the activated liquid which contains micro gas bubbles. The purpose of this invention is to offer new method to produce the activated liquid which contains micro gas bubbles useful for the applications mentioned above. Another purpose is to offer new method realized by the use of the activated liquid. The equipment to produce liquid containing minute bubbles of diameter not less than 10 micrometers has been used for the purification of polluted water and was disclosed in Japanese opened patent application P 2003-53373A. The equipment is preferably used for the purification of the liquid in polluted seas, lakes and marshes, dams, rivers etc. The purification equipment described in this prior invention comprises as shown in FIG. 10, rotor 25 which is installed inside fixed tube 21 and rotated by motor 23, liquid inlet 27 and gas inlet 29 assembled to the wall of fixed tube 21 near one of its ends, stirrer 6 which mixes liquid with gas at first, connecting chamber 31 connected to the other end of the fixed tube, and a pumping means 33 driven by the motor, a set of permanent magnets 35 and 37 mounted on the top surface of a set of linear protuberances 45 and 47 having normal trapezoidal section, top section is shorter than that at bottom, provided on the inner surface of fixed tube 21 and outer surface of rotor 25 respectively, or in a set of grooves formed between adjacent two linear protuberances on the inner surface and/or on the outer surface respectively. While rotor 25 is rotating, liquid and gas are made to flow into fixed tube 21 through inlet 27 and 29 due to pressure reduction in the gap between fixed tube 21 and rotor 25 caused by pumping the liquid out of connecting chamber 31 to the exterior of the equipment. The liquid and gas introduced into the fixed tube in this way are at first mixed mechanically with each other by stirrer 6 and introduced to the gap formed between the inner surface of the fixed tube and the outer surface of the rotor. The liquid first mixed with the gas is then shared, activated, and mixed simultaneously and instantly by the reaction with magnetic field and the intense vibration caused in the liquid when the flow passes the gap between zigzag surfaces, mutually moving in the direction of circumference, formed with each permanent magnet and each set of linear protuberance on each surface of fixed tube 21 and rotor 25 and finally activated liquid, which contains plenty of minute gas bubbles and dissolves a large volume of activated gas, is produced. The liquid, which is activated and contains plenty of gas bubbles in this way, is pumped out to the exterior by means of the pumping means 33 and used for the purification of liquid in exterior source. Although the prior equipment has been successfully used to recover good water environment, further improvement is required for more efficient performance and for wider range of applications.

This invention is also related to technology to decrease or extinguish harmful bubbles generated in the process of industrial production, environmental treatment, treatments of industrial wastes and so on.

This invention is further related to method to produce and use the LIQUID which is activated liquid containing micro bubbles of specific gases for the purpose of sterilization, preservation of freshness, moistening, fire extinguishment, manure, improvement of crumbled structure and exchangeable cation of soil and etc.

This invention offers new method to the prior invention in order to produce more activated liquid containing sufficient number of gas bubbles less than 10 micrometers in diameter (LIQUID) by means of repulsive magnetic field generated by at least one annular activator and/or at least one pair of permanent magnet assemblies.

FIG. 1 is a schematic diagram to explain an example of embodiment of the present invention. Liquid and gas are introduced from exterior sources through at least one liquid inlet 27 and gas inlet 29 which are mounted to the wall near an end of fixed tube 21, respectively in a gap between fixed tube 21 and rotor 25. While rotor 25 is rotated by motor 23, the liquid and gas are rapidly mixed each other by a set of rotating linear protuberances 47 and a set of magnets 37 provided on the surface of the rotor and a another set of fixed linear protuberances 45 and another set of magnets 35 provided on the inner surface of fixed tube 21. When the S pole (or N pole) of the magnet 35 is faced with the same S pole (or N pole) of the magnet 37, it is experimentally confirmed that the diameter of the bubbles become smaller than 10 micrometers, comparing with other cases of configuration of the magnets. When liquid is water and gas is air, best result was obtained with S poles faced with each other. In this way, liquid and gas are mixed, activated and converted into LIQUID during the passage of liquid and gas flow through the gap, of which section is rapidly and repeatedly changing in shape.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

1. Method to Produce LQUID

This invention is related to the production and the usage of activated liquid which contains sufficient amount of micro bubbles of diameter less than 10 micrometers hereafter the liquid is called LIQUID. Comparing with the prior invention by the same inventor, more effective and more applicable method is developed in the present invention.

As shown in FIG. 1, the equipment to produce LIQUID comprises, additionally to the equipment of the prior invention which is already mentioned in relation to FIG. 10, annular activator 81 as shown in FIG. 3 which is composed of far infrared emission material 811 and assisting material 812 such as germanium in between metallurgical phases and emits infrared radiation 813 to activate molecular oscillation of the liquid molecules, and placed between the inlets which can be made from the same material as the annular activator or other material and stirrer 6, and permanent magnet 35 and 37 whose S poles are faced to the gap between fixed tube 21 and rotor 25 as shown in FIG. 2 producing powerful and rapid variation in magnetic field resulting in activated micro liquid clusters due to the electrolysis caused by rapid change in magnetic field. The stirrer is composed of a circular plate 63 fixed to the rotor axis and a set of rod made of ceramic 61 and magnet 62, mixes liquid and gas and generates ion flow while it is rotating. In FIG. 1, 2 and 8, two sets of stirrer are used.

When liquid flows through the inner portion of the activator, molecules of the liquid absorb resonantly energy of the far infrared radiation 81 that is emitted by the emission material even at low temperature. The molecular vibration of the liquid prevents foreign magnetic particles from attaching to the surface of the set of magnet mounted on the fixed tube 21 and rotor 25. Performance of the equipment is further improved to guarantee longer life of operation by preventing the deterioration of magnet otherwise possibly caused by foreign magnetic matters. Especially when the liquid is water, oxygen molecules are taken in water due to hydration, and adsorption of positively ionized air into oxygen atoms of water molecules and also negatively ionized air molecules into hydrogen atoms of water molecules are accelerated. Thus, the annular activator can accelerate and double the effect of activation undergone in the gap formed between the fixed tube and the rotor.

FIG. 2 schematically shows a portion of an example of a pair of magnet assemblies on a plane including axis of rotation and FIG. 4 a half cross sectional view perpendicular to the rotation axis. The south pole of each magnet is designated by S and the north pole of each magnet by N. Permanent magnets 351, 352, 353 etc., which are called a set of permanent magnets 35 if unnecessary to discriminate each other, are mounted on the top surface of a set of linear protuberances 45 having trapezoidal section ABCD formed on the inner surface of fixed tube 21 or in a set of grooves 49 formed by two adjacent protuberances. Permanent magnets 371, 372, 373 etc., which are called a set of permanent magnets 37 if unnecessary to discriminate each other, are mounted on the top surface of a set of linear protuberances 47 having trapezoidal section EFGH formed on the outer surface of rotor 25 or in a set of groove 51 formed by two adjacent protuberances.

As shown in the figures, all the S poles are faced with the gap between fixed tube 21 and rotor 25. When two magnets are faced with the same magnetic pole, magnetic fields of the magnets repulse each other and two strong fields are formed in the gap. This gives strong electromagnetic effect on the physical and chemical state of the liquid corresponding to the field strength, in other words liquid is electromagnetically activated, divided into smaller clusters and micro gas bubbles are generated. When the pole of a set of magnets is reversed, the magnets pull each other and magnetic field becomes rather smooth and peak value is lower than the former case. In other words, activation of the liquid becomes fairly weak and strong effect does not take place.

When rotor is rotating, repulsive magnetic field generated in the gap between the fixed tubes and the motor changes rapidly corresponding to the rotation of the rotor. While the liquid and gas flow through the gap, they are mixed with each other very rapidly due to the mutual rotation of the two zigzag surfaces as a section of them are shown in FIG. 4, and activated by strong magnetic field. It gives random magnetic and also mechanical change at high frequencies to the liquid flow and results in the generation of activated micro clusters and micro bubbles. As a result of this effect, activated liquid which contains sufficient amount of micro bubbles (LIQUID) is produced.

For the efficient production of LIQUID, angle a of side surface AD with respect to the corresponding groove of fixed tube and that b of side surface EH with respect to the corresponding groove of rotor 25 are preferably made equal to a value between 20 to 60 degrees, and depth d between the top surface of protuberance 45 and the top surface of the magnet 35 is made larger than that c between the top surface of protuberance and the top surface of the magnet 37 in FIG. 1. It is to be noted that water flow is sheared depending on the difference in flow speed caused by difference in the depth of concave portion of the surface of the fixed tube and the rotor, so that d could be less than c.

As for linear protuberance in this invention, linear means not only straight but also curved or spiral.

There are variations in the positional relation between the set of magnet and the set of linear protuberance, that is, whole set of magnet is mounted on the top surface of whole set of protuberance as shown in FIG. 5, a set of magnets is mounted on the top surface of a set of linear protuberances formed on the inner surface of fixed tube 21 and another set of magnets is mounted in a set of the grooves formed on rotor 25 in FIG. 6, and vice versa in FIG. 7.

FIG. 8 shows another embodiment of the present invention. Motor 23 is installed at the bottom of the equipment. There is no difference in substantial functions as mentioned above.

It was experimentally found using laser scattering measurement that the equipment operated at the rotating speed of 1500 rpm to produce 40% of bubbles being distributed in the diameter range of 5 to 10 micrometers, and 20% in 2 to 3 micrometers. And the change in pH caused by the diffusion of water ion was observed. It proved the production of micro bubbles. Moreover, it was found that activated bubbles of less than 10 micrometers in diameter can stay stably much longer in liquid, causing the increase of the probability to activate the liquid atoms and molecules, resulting in increase in dissolved oxygen leading to faster and more efficient purification.

LIQUID is characterized by

-   (1) LIQUID mainly composed of activated liquid wherein gas is     dissolved and micro bubbles of diameter less than 10 micro meters     containing the same kind of gas. -   (2) LIQUID mainly composed of activated liquid wherein specific gas     such as hydrogen is dissolved and micro bubbles of diameter less     than 10 micro meters containing the same kind of gas. -   (3) Any kind of gas can be used for LIQUID. However, air, oxygen,     ozone, nitrogen, carbon dioxide or hydrogen, or mixture of these     gasses can be preferably used.

LIQUID exhibits the following effects,

A. Increase in the contact area between liquid and gas. As the diameter of a bubble decreases, the total surface area of the bubbles of the same diameter. It implies that reaction speed becomes much faster if bubbles of smaller diameter are used.

B. Decrease in surface tension. Looking at water molecules, each molecule always moves randomly as expressed in Brownian linear and rotational movement and also repeats elastic collisions. As the surface tension decreases, bubbles break during sedimentation affected by Brownian movement and dissolved oxygen increases. The life of bubbles becomes much longer and they move in regular flow as transversal wave does.

C. Electrolysis. Due to the reaction with magnetic field, water molecules are ionized to generate hydroxyl ions, and clusters are divided into smaller ones having sterilization and cleaning effect. In addition, spin motion of water electron is induced and deoxidization takes place.

D. Regulated molecular movement caused by magnetic field. Molecular movement is regulated to rotational one in a direction and chance to react with other molecule decreases.

E. Sterilization and preservation of food

When micro bubble disappears, H ion, OH ion and H302 ion are developed and destroy virus. Bacteria are destroyed by decrease in oxidization and reduction potential, surface tension, osmotic pressure. As the micro bubbles are charged with minus potential, bacteria usually charged with plus potential die caused by the exchange of ions. The bacteria of incomplete formation of nucleus membrane are killed selectively due to ion exchange and potential difference caused by the penetration of minus ion. Those of complete formation are not affected. Bladder of blue-green microbe is destroyed by minus ion and then the microbe dies. Micro bubbles selectively react with and kill bacteria having plus ion. As good microbes have minus ions, the micro bubbles give no effect to them.

The color of an agricultural product changes when its solution has plus potential and is oxidized in air. Freshness of food is preserved by preventing it from oxidization by ion exchange between ion in the solution and minus ion charged to LIQUID.

F. LIQUID having new function

By the method disclosed in the present invention, drinking hydrogen water or oxygen water having less oxidization and reduction and long dissolving period can be produced by dissolving hydrogen or oxygen in the gap of water molecules respectively caused by powerful self compression mechanism of micro bubbles.

G. Storage of gas in the form of hydrate

Hydrate is the compound which is composed of gas molecules taken in a cage formed by water molecules. Gases to cause global warming, such as carbon dioxide, nitride, methane, CFC, HCFC, HFC etc. form hydrate when they are mixed with water.

Micro bubbles are partly characterized that they dissolve the gas inside in liquid until they disappear in the liquid, because of totally larger surface area and the effect of the increase in pressure inside. Gas hydrate is generated by taking advantage of the compressibility of micro bubbles, that is, pressure inside of the bubbles is higher than the surrounding. Bubbles become smaller as the gas is dissolved in liquid. However, the pressure becomes higher as bubble diameter decreases because of the increase in surface tension corresponding to the decrease in bubble diameter and reaches critical pressure where nucleus of hydrate is generated in the surrounding liquid. Once hydrate starts to be generated, it continues to grow. Storage of the warming gas can be done without the equipment of big scale and heavy investment but can be done with simple equipment based on the method disclosed in this invention.

The pressure necessary for the generation of hydrate is less than that of saturated vapor of warming materials so that this invention offers economic means with lower energy for the separation of the hydrate from liquid.

H. Method to purify water environment polluted by PCB and/or dioxin, to remove smell and to decomposition of volatile organic compound.

When dirty and muddy water is made randomly moved and flow in magnetic field, metal ions are spread and increase thermal energy of water molecules and metal ions attracting water molecules. By these cooperative effects, high temperature is developed in local areas on boundary surface of micro bubbles. The high temperature areas diffuse and contact with PCB. PCB is then, decomposed with the high temperature.

In the equipment based on the method disclosed in this invention, liquid is powerfully and rapidly stirred and supplied with energy of compression and expansion, and also rotation.

PCB moves to boundary surface of bubbles because of the effect of shedding water and electric field, and is decomposed caused by the energy of molecular oscillation in the boundary. Even if PCB is caught in a group of water molecules, electromagnetic field and metal ion accelerate molecular movement of polluted water and as a result it becomes easy to separate PCB from water. As metal ion such as Mg, Na, K having excellent property for the removal of chlorine exists in the PCB, chlorine is pulled off the substances when they meet with one of the ions. Combined with these effects, benzene rings of PCB are broken and discomposed into carbon dioxide and chlorides.

Smell and volatile material are introduced in the equipment based on this invention and made dissolved in water and decomposed by the effect of oxidization and reduction, and also decomposed by the energy of molecular oscillation in local areas developed by the reaction of randomly and rapidly moving water flow with electro magnetic field in the same way as PCB.

2. Method to Use LIQUID

2.1 Method to Extinguish Bubbles

By the use of LIQUID, the present invention offers new and low cost method to extinguish the bubbles, without additive, which give harmful effect in industrial process, such as in chemical, polymer or ferment plant.

In conventional physical-mechanical techniques, expensive and energy consuming equipment is required to give pressure, heat or vibration to a large volume of liquid needed for the extinguishment. In chemical extinguishment, additive is necessary and increases cost. Additive is not applicable when it is undesirable to use.

It is experimentally found that group of stubborn bubbles in polymer emulsion disappeared in a short time when equipment to produce LIQUID is operated. Although the phenomenon has not been fully understood, it is estimated that the surface tension of the liquid around them is caused to decrease by LIQUID and liquid around smaller bubble becomes more viscous and the larger bubbles can not sustain themselves and are broken when stable bubbles produced by the equipment collide with them. All needed is simply to place and operate equipment in the liquid to extinguish bubbles and nothing else is necessary. The equipment can be used for the extinguishment is any one capable of generating micro bubbles less than 10 micrometers in diameter.

FIG. 9 is schematic diagram to show the basic concept of the method for the extinguishment of bubbles. It is good enough to place the equipment 10 together with supporting means at bottom surface of the container 11 where liquid to be treated for extinguishment of bubbles are contained and to operate the equipment bringing soft tube 12 connected to the air inlet 29 above liquid surface.

2.2 Method to Use LIQUID for Other Applications

The present invention is related to minute droplets and method to produce them for the purpose of sterilization, moistening, fire extinguishment, manure, improvement of crumbled structure and exchangeable cation of soil etc. by the use of LIQUID

Magnetic treatment of liquid especially of water has attracted a great deal of interest. Although reason is not fully found yet, the treated water shows unique characteristics such as increase in penetration capability, protection or removal of the rust caused by contact of ferrous metals and prevention of attaching calcium carbonate to the wall of the pipe.

On the other hand, as the technology to minimize bubbles has greatly advanced, bubbles less than a few micrometers or less in diameter contained in liquid especially in water can be produced by the method disclosed in this invention. It becomes clearer by the experience of the inventor that the micro bubbles show characteristics remarkably different from that of larger bubbles, as mentioned previously, for example the bubbles are stable and stay in water for a long period without floating or dispersing and water containing oxygen bubbles becomes more active to bacteria or microbes.

At present, LIQUID has been applied to the treatments which are operated in liquid as already mentioned and there has been no application wherein the minute bubbles are sprayed in the form of droplets or mist.

Therefore, the present invention offers new type of method to use LIQUID and also the liquid which contains minute bubbles developed by the method disclosed in Japanese opened patent application P2003-53373 or equivalent methods.

Based on the result of long term investigation and experience on the generation of micro bubbles and magnetic treatment for the purification of water, the embodiments of the present invention are

-   (1) Method to use liquid which contains minute bubbles of specific     gas, in the form of droplets or mist. -   (2) Method to use liquid which is magneto-electrically activated and     contains minute bubbles of specific gas, in the form of droplets or     mist. -   (3) Methods of (1) and (2) wherein LIQUID is produced by equipment     which mixes liquid and gas supplied through inlets, or equipment to     produce minute bubbles, or most preferably by the method already     disclosed in this invention. -   (4) Methods of (1) and (2) wherein LIQUID is produced by equipment     which mixes liquid and gas, or equipment to produce minute bubbles,     or most preferably by the method already disclosed in this invention     and supplied to proper sprayer. -   (5) Methods of (1) and (2) wherein the gas is air, oxygen, ozone,     nitrogen, carbon dioxide or hydrogen, or mixture of these gasses. -   (6) Methods of (1) and (2) wherein said droplet is of water and     water containing solved matter. -   (7) Methods of (1) to (6) wherein LIQUID is supplied to the inlet of     at least one sprayer.

According to the present invention, droplets and/or mist of new characteristics is produced and expected to be applied to sterilization, cleaning, fire extinguishment and plant processing by spraying liquid which contains minute bubbles and/or those treated magnetically.

Mixer of gas and liquid or equipment to produce minute bubbles, which is defined here as those of diameter less than 50 micrometers, to be used for the present invention includes any equipment that is provided with liquid and gas inlet and produces bubbles of required diameter and/or additionally provided with function for magnetic treatment. Production equipment of minute bubbles disclosed in Japanese opened patent application P2003-53373 and production method of micro bubbles in FIG. 1 is especially suited for the object of the present invention.

Any liquid and gas can be applied to the method disclosed by the present invention. Main gas to be used for the purpose of this invention may be air, oxygen, ozone, nitrogen, carbon dioxide and hydrogen from the practical view point.

As for spray, the connecting chamber 31 in FIG. 1, 8 and 10 can be used by modifying it to be of closed chamber connected with at least one sprayer having spray nozzle. If necessary, the nozzle is provided with the device utilizing ultrasonic waves and/or any other means to accelerate dispersion of the liquid.

When much smaller liquid droplets or much more powerful spray is needed, the water which is magnetically treated, contains minute bubbles and/or magnetically treated, produced by minute or micro bubble production equipment, must be supplied to proper sprayer.

According to this invention, it becomes possible to sterilize air spaces, wall surfaces, utensils and other objects by spraying water which includes minute ozone bubbles. It is usually necessary to isolate object to be sterilized in a closed space and to introduce ozone gas into it. According to this invention, ozone is kept in liquid droplet in the form of minute bubbles and released slowly from the liquid droplet attached to the object to be sterilized and sterilization takes place only in the vicinity of the droplets. No ozone gas is released in air while water droplets are sprayed in open space. Therefore, spray of water droplets containing ozone bubbles does not give harmful effect to human body.

When the diameter of bubble is smaller than one micrometer, it is very stable and can be kept in droplet for a long period. LIQUID can be used for the storage of gas in safe.

The LIQUID (water) which contains nitrogen or carbon dioxide can be used to extinguish fire by spraying the water to fire source. The LIQUID can be sprayed more concentrated to the source with less contamination than the ordinary fire extinguishment which generates large gas bubbles. Effect of lowering temperature by water and of shielding by inactive gas is evident at the same time.
